Puddle Glum

Saku was feeling hungry one summer's day, so she decided to make herself a strawberry jam sandwich.
She spread the jam on the bread and when she had finished making her sandwich she went to pick up the jar of jam, only to find that it was now sitting in a puddle where previously there had not been one.

Where did the puddle come from??

Hint

Answer

The water had condensed on the jar from water vapour in the air, because she had been keeping the jar of jam in the refrigerator. The water then ran down the outside of the jar, pooling on the bench.Hide

When I was a little kid, I always drank water with ice in it. When I lifted the cup off of the table, I would notice a small pool of water on the table where the rim of the cup had been. I used to think that my cup had a small leak, until I learned otherwise, when I was older!

Ugh. Try some CONSTRUCTIVE criticism in the future guys, if you keep treating people like this nobody will make you any puzzles to do at all. Geez.

And yes I think everyone keeps jam in the fridge..all my jars say "refrigerate after opening"..it's to make it keep longer not to prevent ants- I don't think they could get in if you screw the lid on properly!

The whole point of making traditional jam is to prepare fruit so that it will keep.

That's done by boiling all the germs out of it and putting in so much sugar that micro-organisms can't live in it (micro-organisms can't live in pure sugar which is why a bowl of sugar doesn't go off).

If jam is made right you shouldn't have to refrigerate it to keep it good... however most mass produced jams these days are not made using traditional methods because such jams aren't as pretty or easy to spread.

could the jam really leave a puddle in the time it takes to make a sandwhich? I figured it out though. It makes me feel like i sat through so many years of science for something--i can actually understand this a little. only two more yrs (i am a h.s. sophomore) of science. Science is fun!!
